BOLSTER FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 638,105, dated. November 28, 1899.

Application iiled January 6, 1899.

To all wiz/0m t may concern:

Beit known that I, JOHN C. FoE'rINEE,a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bolsters for Railway-Cars, of which the following is a specification.

The object of my invention is to provide a simple, economical, and efficient bolster for railway-cars; and the invention consists in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawings, Figure lis a side elevation of a bolster constructed in accordance with my improvements shown in connection with a portion of the transom; Fig. 2, a plan View of the same, partly in section, looking at it from the top; Fig. 3, an end View of the mechanism shown in Fig. I; Fig. 4, a cross-sectional view or modification taken on line 4 of Fig. 5, and Fig. 5 a plan view of a modiiied form of bolster shown in cross-section.

In constructing a bolster in accordance with my improvements I make I-beams A and Al and arrange them lengthwise of the bolster, with flange portions a, and a. in horizontal planes, and the connecting web portions d2 in vertical planes, as shown particularly in Figs. 3 and 4. The lower flange portions are connected together by means of the pieces of sheet metal B, which may also form springseats, and sheets or webs C are used to connect the upper iianges together, to which the center plate D is secured. These webs or sheets of metal are preferably riveted to the lower and upper flanges of the I-beams, though they may be otherwise secured, if desirable or necessary.

In order to provide ways for the transompillars E and E to slide in, the iiange portions of the I-beams adjacent to each end are notched at a3 and a4 and at the outer lateral Serial No. 701,339. (No model.)

edges. The transom-pillars, as shown particularly in Figs. 2 and 3, are loosely tted to these notches, so that the bolster may freely slide up and down on the same. The notching of these I-beams at their outer lateral edges dispenses with the necessity of using eXtra castings or forgings to form the guides for the bolster upon which it may slide on the transom-pillars and at the same time provides a simple, economicakand eiiicient structure.

In Fig. 4 I have shown a modied form of bolster in which the I-beams are reinforced and held together by means of an inverted- U-shaped piece G, which is riveted to the web portions of each of the I-beamsand eX- tends across and iills the space between the upper flanges.

I claiml l. Abolster for railway-cars, in which there are combined two I-beams extending lengthwise thereof with their `flanged portions arranged in horizontal planes and provided with parallel notches or indentations at or near each end and on the outer lateral edges to receive the transom-pillars, and plates connecting the lower flanges of the I-beams together, substantially as described.

2. A bolster for railway-cars, in which there l are combined two I-beams extending lengthwise thereof with their flanged portions arranged in horizontal planes and provided with parallel notches or indentations at or near each end and on the outer lateral edges to receive transom-pillars, means connecting the lower iianges of the I-beams together, and an inverted-U -shaped piece interposed between the I-beams and connected with the webs of the I-beams, substantially as described.
